WADA told VeloNation on Friday that it had accepted a request from Contador to give him more time. “WADA acknowledged a decision from CAS to postpone the hearing following a request made by Alberto Contador,” a WADA spokesman said.

“Ideally, WADA would have liked a decision ahead of the 2011 Tour de France, but accept that other considerations have prevailed to ensure even greater fairness to Mr. Contador.”

Further details behind the decision have not been made public. WADA has decided to keep its appeal separate to that of the UCI. This hints that it may be pursuing different charges, or approaching the case from a different angle.

The two bodies have combined appeals in the past, most notably their joint action against Alejandro Valverde.

Speaking last week, Tour organisers ASO said that they were still hoping that a decision could be reached prior to the race. “We want to believe that a decision will be made before the start,” race director Christian Prudhomme told AFP.

“We are surprised because the CAS had repeatedly announced that the decision would be made before the start. The schedule was set with a hearing scheduled between 6 and 8 June. We can only repeat what we said since last autumn: hopefully there will be an answer before the Tour.”

ASO’s response to this evening’s news will therefore be an interesting one. Under UCI rule rule 2.2.010, organisers can block riders in certain circumstances.

“The organiser may refuse permission to participate in – or exclude from – an event, a team or one of its members whose presence might be prejudicial to the image or reputation of the organiser or of the event,” states that rule. “If the UCI and/or the team and/or one of its members does not agree with the decision taken in this way by the organizer, the dispute shall be placed before the Court of Arbitration for Sport which must hand down a ruling within an appropriate period. However, in the case of the Tour de France, the dispute shall be placed before the Chambre Arbitrale du Sport.”

The fact that Contador’s legal team are insisting that his positive was accidental and due to food contamination means that they would fight any such attempts to prevent him from riding the Tour. A battle prior to the start between them and ASO would be messy, but so too would be the fallout if he is ultimately found guilty after riding – and possibly winning – this year’s race.

Contador insists he is innocent and has said that he has never doped. He won the Giro d'Italia on Sunday, his sixth Grand Tour victory.
